Specification of Letters Patent.

Application filed Februar; 23, 1911 Serial No. 610,240. Renewed October 17, 1913. Serial No. 795,789.

To all whom it may concern Be it known that I, Foniiri BAIN, a citizen of the United States, residing at La Grange, in the county of- Cook and State of Illinois, have invented certain new and useful Im- Sheet-Metzil Receptacles, 'of following is a specification.

invention relates to improvements in sheet metal receptacles,'such as Wet barrels, and the like; and one of the objects of my invention is to provide an improved means for joining the such receptacles.

A further object of my invention is to provide an improved receptaclewherein the and subsequently secu-red together by means Ofa ring member, without the'necessity of deforming or'distortingeither the body or thehead member in the assembling operation, and whereby a rigid, strong, and

' tight structure is produced.

- invention,

Other and further ob ects of my invention' will become apparent to those skilled in the art from the following specification taken in'conjunction with the accompanydrawing, whereinigure 1 indicates in broken elevation a receptacle embodying my invention, one end thereof being shown in central vertical section; Fig. 2 represents in section fragments ofa receptacle embodying my invention, the body and head with a clamping ring member ready for application thereto; Fig. 3 is a similar view showing the ring member applied to the body and head before the rolling operation; and Fig. ,4: is a similar view showing the completed joint.

' For purposes of clear disclosure of my I have illustrated a barrel as a proper exemplification thereof, and in the convex shape,

structure shown 5 indicates ill cylindrical body and 6 a disk-head of ordinary concavoeach being formed of sheetmetal. The head 6 has the usual rim-flange 7 at its outer edge, interiorly interfitting into the rim portion 5 of the body, so that its free edge is flush with the end edge of the body. It will be understood that where the receptacle is a barrel, both ends are made alike, but for purposes of definition directions will uniformly be referred to as they appear in Figs. 2 to -1, upper meaning The angle;

toward the middle of the barrel, and lower meaning toward the end of the barrel.

8; formed between the rim "erably formed by body and the, head of portion 7 and the transverse Web or disk of the head (which I will'term the rim-angle Patented Jan. 5, 1915.

of the head), preferably seats against a shoulder 9, formed in the peripheral wall of the body at the upper extremity of. the rim portion 5 thereof, the shoulder being prefan. internal bead afiording an exterior circumferential channel 10.

The U-shapedclamping ring 11 is made of suitable malleable metal, such as soft iron,

or steel, to provide concentric exterior and interior limbs 12 and 13, separated by the annular groove or recess 14, as shown in Fig. 2, the outer limb being taller or inturned substantially at right angles to the limb, the juncture, '16, of the upper and exterior surfaces of the flange and limb re-,

spectively (whichI will term the bearing edge of said inner limb) lying in a plane lower than the free edge 17 of theexterior wire18 of a ductile material softer than thatof which the remainder of the structure is composed,--such as lead, solder, or the like,so that. it will be compressed or spread in the process of rolling the ring in place, to act as an auxiliary sealing means for the joint tobe made.

Fig. 3 shows the members of the structure ready for final compression of the clamping ring to complete the joint, the' rim portions 7 and 5 of thehead any body lying'in the groove 14 of the clamping ring with the lower edges of said rim portions resting on the wire 18 and with the bearing edge, 16, of the inner limb of the clamping'ring, interfitting with the rim-angle 8 of. the head, the free edge 17 of the exterior limb ex tending above the plane of said angle 8. Incompleting the joint, the parts are forced into the position shown in Fig. 4, as by a suitable rolling operation. The limbs of the ring are brought into intimate contact with the contiguous portions of the body and head structures throughout substantially their entire extent, and the free edge in aplane above the bearing edge 16 of the opposing limb 13 and forced into the groove rolling, in the'barrel body,

deeper than the inner limb. .The inner limb, 13, is preferably provided with an annular flange 15,

or-channel 10 of the receptacle body to clamp the shoulder 9 of the bodyand the rim-angle kln the rolling operation, the internal "flange lfi of-thc ring member serves as an 5 abutmentjforan anvil orbase-roll, so that the pressure roll may be applied against the end 17 of the exterior limb to exert stress onjthepressure'line 20-20 to turn said edge into the groove 10 and to produce the desird-ycompression of clamping action betwlanlthe bearing edge 16 of the inner limb and-the free edge of the outer limb, without :straining the head or rim flange. It is usu ally convenient and preferable to provide the-channel orflrooveYlO in the receptacle 'bodypreliminarily to the assembling operation, and in such cases the subsequent assembling of the'parts is effected without distortion or displacement of any portion of the vbarrel or head structures; but it will be ap parent that when so desired, the groove 10 may ,bemade at the time of, and incidentally to, jthefl'inturning of the free edge 17 of the clamping ring.

flkltgiwil'l be observed that the joint is primarily made as a result of rolling the longer limb of the U-shaped clamping member over the e'dge 'of the shorter limb of said ring member, clamping similarly contorted portions of the body and head members in the angle formed between the edges of the longer and :shorterl-imb members, but the joint is of course aided by the intimate contact'iof the parallel portions of the limb members with the contiguous cylindrical rim portions of the body and head, and by the sealing effect of the ductile wire 18. By forming the joint with the outer limb member inrolled, it will be observed that the principal joining effect is secured at the rimangle 8 normal to the head structure without any distortion whatever of the head, said rim-angle being adequately supported by the clamping ring flange 15, so that neither in the rolling operation nor in use is it subject to any such strain as to render it liable to rupture. Thus, by the arrangement of the inrolling of the longer outer limb over a bearing edge of the sh rter limb, entering the normal angle of the ead, I am enabled to secure substantially a right-angle joint without imposing undue strain on any. portion of the sheet metal which would render it liable to rupture.

The .clamping ring 11 is preferably so formed that its lower or standing edge provides an end bearing surface alining with. only the'inner limb 13, as indicated at 21, Fig. 45. To this end, the lower portion of the clamping ring is chamfered as at 22, the object being so to locate the endbearin'g of the ring below the innerlimb 13 that the of the ring limbs rather than to spring them weight of the barrel, or shocks imparted to the lower edge. ofthe ring, tends to lift the "inner limb l3,"with, .a resultant tendenyfto tighten the joint between the upper edges 1 VVhile I have herein described only asingle embodiment of'my invention, it will be evident that the illustrative eXemplific'a-" tion is susceptible of changes without departure from the spirit of the inventionand within the scope of the appended-claims.

What I claim is: l

1. A receptacle "comprising a head, a body, and a clamping member, said clamp- 0 ing member having substantially arallel concentric inner and outer limbs etween which portions of said body and head mem ber are inclosed, the edge of one limb being laterally deflected toward and above the upper bearing edge of the other limb, to clamp between said edges portions of the head and body, and portions of said head and body clamped between said edges being compressed.

2. In a metallic receptacle, the combination with a body and a flanged head interfitting to provide a rim, of a clampin mem ber'having parallel concentric lim s embracing said rim, the inner limb of the clamping member having its upper bearin edge fitting in the rim angle of the head, and the outer limb having its free edge inwardly deflected in a plane above the head, to clamp said rim-angle and a portion of the body 10 against the bearing edge of said inner limb.

3. In a inetallic receptacle, the combina. tion with a body and a flanged head presenting concentrically interfitting rim portions, of a clamping ring having concentric limbs substantially embracing said rim portions, the inner limb of said ring having its end inturned to form a substantially right angle flange with its bearing edge engaging the head at the rim-angle thereof, the outer limb of said ring'havmg its free edge inwardly deflected in a plane above the head to clamp the rim-angle and a portion of the body against the bearing edge of the said inner limb. v

4. In a metallic receptacle, the combination of a-body member exteriorly grooved to provide an internalv shoulder, a head i member flanged and interfitting in said hottom member and bottoming against said 120 nal groove formed in its wall near the end thereof, a head member having an interfitting concentric rim bottoming a ainst said internal shoulder, and a U-shape clamping .member one limb thereof within said run portion and the other limb having a portion thereof lying within said groove to clamp the parts together. 7 I

' 6. A receptacle comprising a head, a body, and a clamping member, said member having substantially parallel inner and outer limbs between which .portions of said head and body are inclosed, the edge of the outer limb being inturned toward and above the upper bearing edge-of the inner rim to clamp said parts together.

7. A receptacle comprising a head, a body, and a clampin member, said member having substantial y parallel shorter and longer limbs between which portions of said head and body are inclosed, the edge of the longer limb being turned toward and above the upper bearing edge of the shorter limb, to

clamp said parts together the body and head parts being compressed between said limbedges, and the free standing ed e of the clamping member being circum erentially chamfered so as to leave the wei ht-bearing surface only under said shorter b.,

8. A receptacle com rising a head, a one piece circumferential y continuous bod and a clamping member, said head and b0 y having interfitting cylindrical portions and said clamping member having integral-concentric limbs spaced apart by an annular recess in which said cylindrical portions are received, said inner limb having a bearing edge at a point spaced from the bottom of said recess, and the salient edge of said outer limb bein inturned toward and above said bearing e ge to clamp said head and body portions thereagainst.

In testimony whereof I hereunto set my hand in the presence of two witnesses.
